Complete and balance the following half-reaction in basic solution Mn2" (aq) – MnO2(s) 身

Aqua regia, a mixture of concentrated HNO3 and HCl, was developed by alchemists to “dissolve” gold. The process is a redox reaction with the following simplified skeleton reaction: Au(s) + NO3- (aq) + Cl- (aq) AuCl-4 (aq) + NO2 (g) (a) Balance the reaction by the half- reaction method (b) What is the oxidizing and reducing agents? (c) What is the function of HCl in aqua regia?
